To all whom t may concern.'

Be it known that l, TrrnoDoRr-i GnNsMEm a citizen of the United States, and a resident of the city of Portland, in the county of Multnomah and the State of Oregon, have invented a new and useful Improvement in a- Lawn Sprinkler, of which the following is a specification.

This invention relates to new and useful improvements in lawn sprinklers.

rlhe primary object of the invention is to provide a sprinkler which will Ydiffuse the streams of wat-er discharged therefrom into the finest possible yunits and will evenly distribute the same overa very vlarge area,

A further object of the invention is to provide a sprinkler which may be adjusted to vary the area covered during operation irrespective of the amount of water discharged or the pressure at which the water is fed to the device.

A still further obj ect of the invention is to provide a sprinkler constructed of .a minimum number of separable parts, which may be easily repaired or replaced.

lAnother object of the in-vention isto provide a sprinkler of the above noted type which, when placed, will remain in operative position, and one which will 1operate easily and with-a minimum amount vof friction.

Other objects and advantages of the invention will be apparent during the vcourse of 4the following description.

In the accompanying drawing forming a part of this specification and .in which like numerals are employed to designate like parts throughout the same,

Figure l is a side-.elevational view of the assembled sprinkler with a hose connection for feeding water thereto from a source of water supply, not shown,

Figure 2 is a plan view of the sprinkler head showing the diffusing blades and the nozzles for impinging the water against lthe same,

Figure 3 is a partial crOssvsect-ional view thru the head of the sprinkler and shows lthe internal construction of the same,

space over which the water will be diffused, and i Figure 5 is an end elevational view of the nozzles of the sprinkler head without the diffusing means employed in connection therewith, the dotted positions showing the adjustments of the nozzle outlets.

Briefly described, my sprinkler device includes a tubular standard or support upon which a sprinkler head is rotatably mounted. During periods of idleness, the sprink ler head rests `upon a supporting portion of the tubular standard, but upon being placed in operation, thesprinkler head is automatically elevated above the said supporting portion and rotates freely aboutl a ypivot member. This sprinkler head `includes a suitable number of discharge nozzles which are independently adjustable for directing the streams of water against a plurality of diffusing surfaces at different elevations, thereby causing the streams to be broken up into fine particles and deposited over areas of different radii. The plurality of diffusing surfaces are carried by a disk rotatably mounted on the nozzle carrying poltioirof the sprinkler head and, during operation, revolve in the direction opposite to -that taken by the nozzles during their travel about the supporting' standard.

It is to be understood that the disk with its diffusing surfaces may be dismounted from the nozzle carrying portion of ythe sprinkler head and the device successfully operated without the same. The spray, however, does not consist of as finely divided particles of water when the diffusing surfaces are knot used as when the said surfaces form a part of the operative device.

For a better and more complete detailed description of my sprinkler,reference is had to the accompanying drawings wherein for the purpose of illust-ration is shown apreferred embodiment of this invention. AThe numeral l designates a hose orvothertubular conducting member thru which water is conveyed from a source of supply, not

shown. This hose l is providedl wit-h a screw attachment means or connection by means ofwhich it may be removably fastened to the nipple 3 carried byone opening of the T-coupler 4:. @ne of the remaining openings of this T-coupler 4: is threadedly connected to a tubular standard or .shaft 5, while the remaining opening of the T- coupler is threadedly connected to a section of piping 6 which is 'externally screwthreaded at its upper end and internally screw-threaded at its lower end. The lower, internally screw-threaded end of this member 6 is adapted to be connected to the rod 7, having a pointed lower end 8, by means of the external Screw threads 9 tor-med on the said rod. A collaror disk 10 is selectively threaded upon the threaded portion 9 of the rod 7 and acts as a stop when the I'od 8 is driven into the soil underneath the lawn to be sprinkled bv the device. It is E? to be understood that the threaded portion move axially in respect thereto.

9 of the rod 7 permits the latter to be telescopically connected with the piping G so that the said rod will project therefrom for diierent portions of its length, thereby providing a rod of suitable length to adapt the same to be driven into soil of different degrees of hardness. The collar 10 threaded upon the rod 9 may be employed, also, as a lock nut for preventing the rod -7 from becoming loose i'rom the piping 6.

The upper end of the tubular standard or shaft 5 is internally screw threaded for being connected to the ,threaded end 18 of the tubular bushing 17 having the borer17a and the enlarged head 16. This tubular bushing is employed :tor loosely connecting the nipple `11 to the tubular standard or shaft 5 for permitting the said nipple to freely rotate about the bushing 17 and to j This nipple 11 is threaded at its upper end 12 for connection with the threads 12a ot the hollow heXagonally-shaped member 14. The' bore of this member 14 is of relatively large diameter to Yform the recess or chamber 15 while the remaining portion 14a of the bore of the member 14 is of less diameter than the recess or chamber 15.

Threadedly connected to the upper portion of the hexagonal member 14 and in horizontal valinement with the reduced portion V14a of the bore of the membery 14 are the inner threaded ends of the nozzle members 19 and 20. These nozzles are crooked or bent upon themselves at their outer ends 26 forcausing the streams of water discharged there'lfrom to be directed substantially radially inwardly. In Figs. 4 and 5 these nozzles are shown in full and dotted line positions for illustrating the adaptability of the nozzles to be rotated, by means of their threaded connect-ions with the member 14, to permit the discharge extremities of the said nozzles to be located at different elevations. l

Threadedly connected to the upper end of the member 14 is a bolt 21 having rotatably mounted thereon a two-part collar bushing 22 which is employed for clamping the disk 23 therebetween. This disk is provided with struck up fins or projections 24 which extend tangentially in respect to the axis of the disk. While these tins or projections 24 are shown as having upper` contours constituting segments of circles, it is to be understood that I do not desire to limit myself to this particular formation as many other contours or shapes will give as equally good results.

The operation of this sprinkler may be described as follows It is to be understood that the sprinkler is iirst properly located in respect to the portion of a lawn to be sprinkled and the rod portion 9 is driven into the soil at that point. The water supply is then connected with the hose 1 and the flow of water started. The water in passing upwardly thru the hollow standard 5 will pass thru the bore 17a of the bushing 17 and will enter the recess or chamber 15 and the bore 14a. This upward pressure of water will cause the members rotatably connected to the hollow standard 5 by means of the bushing 17 to be elevated for producing a gap at 13 between the lower end of the nipp-le V11 and the upper end of the hollow standard or shaft 5. The said nipple 11 will then rotate about the bushing 17 with very little resistance. The streams of water discharged from the nozzles 19 and 2O will be directed against the diiiusing tins or projections 24 and will be broken up into finely divided particles and sprayed over a large area of lawn. The nozzles will be caused to rotate in one direction while the streams of water impinging against the fins or projections 24 will cause the disk23 to rotate in the o-pposite direction. It will be understood that by adjusting the nozzles 19 and 20 so that their discharge extremities will be positioned on different elevations, the water will be diffused or sprayed over different Sized areas.

In Figs. 4 and 5 the sprinkler embodying this invention is illustrated without the disk 23 and the diffusing ins or projections 24. lVhen the said disk 23 is done away with, the device may be used successfully, but a dilferent sprinkling etlect is obtained. The nozzles may be adjusted so that the streams of water discharged therefrom will merely be thrown outwardly Jfrom the standard 5, or the said nozzles may be adjusted so that the streams of water discharged therefrom will impinge against each other and be broken up into a tine spray.

lIt is to be understood that. the forms of this invention herewith shown and described I-Iaving thus described the invention, I claim l. In a device of the type described, a hollow standard, means for feeding water thereto, a hollow head rot-atably mounted thereupon, a disk having a plurality of tins rotatably carried by said head, and a plurality of nozzles carried by said head and adjustable to discharge water against said fins at dierent elevations.

In a device of the type described, a hollow standard, means for feeding water thereto, a hollow head rotatably mounted thereon and movable axially in respect thereto, a disk having a plurality of strucloup tins rotatably carried by said head, and a plurality of nozzles carried by said head and adjustable to discharge water against said ns at different elevations.

5. In a device of the type described, a tubular standard, a hollow head rotatably mounted thereon, a disk having a plurality of struck-up tangentially extending fins carried by said head and rotatable in respect thereto, and a plurality of reaction nozzles carried by said rotatable head and disposed to cause rotation of said head and to discharge water against said fins to cause said disk to rotate in an opposite direction from said head.

6. In a device of the type described, a vertically extending conduit having external threads at its upper end, a bushing threadedly connected to the upper end of said conduit, a head rotatably carried by said bushing, a disk carried by said head to rotate in respect. thereto and having fanlike blades projecting upwardly therefrom, and reaction nozzles adjustably carried by said rotatable head and disposed to cause rotation of said head and to discharge water against said fan-like blades to cause said disk to rotate in an opposite direction from said head. y

7. In a device of the type described, a perpendicular tubular standard adjustable longitudinally, means lfor feeding water to the bore of said standard, a head rotatably mounted upon said standard and having a pocket for the reception of water from the standard, a plurality of discharge nozzles adjustably carried by said head 'for enabling the extremities of the same to be positioned at dilferent elevations, and a disk having stuck-up lins rotatably carried by said head and adapted to di'licuse the water discharged from said nozzles.

In testimony that I claim the foregoing as my own I hereunto attach my signature in the presence of two witnesses.
